DETAILED DESCRIPTION

[0024]In the embodiments of the disclosure, the term “and/or” describes a relation of associated objects, which indicates three relations, for example, “A and/or B” indicates that A exists alone, A and B both exist, and B exists alone. The character “/” generally indicates that the associated objects prior to and after the character “/” is an “or” relation.

[0025]The term “multiple” in the embodiments of the disclosure refers to two or more, which is the similar for other quantifiers.

[0026]Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure.

[0028]It is understandable that although the terms “first”, “second”, and “third” may be used in the embodiments of the disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the term “if” as used herein can be interpreted as “when”, “while” or “in response to determining”.

[0029]The technical solutions in the embodiments of the disclosure will be described clearly and completely below in combination with the accompanying drawings in the embodiments of the disclosure. Clearly, the described embodiments are only a part of the embodiments of the disclosure, and not all of the embodiments. Based on the embodiments of the disclosure, other embodiments obtained by those skilled in the art without inventive works all fall within the scope of protection of the disclosure.

[0030]Embodiments of the disclosure provide a wireless local area network (WLAN) sensing measurement method, a WLAN sensing measurement apparatus, an electronic device and a storage medium, to provide a method for feeding back a measurement result in a Non-trigger based (Non-TB) sensing measurement procedure.

[0031]The method and apparatus are based on the same application conception, and since the method and apparatus solve problems based on similar principles, the implementations of the apparatus and the method can be referred to each other, and the repeated contents will be omitted.

[0032]FIG. 1 is a flowchart of a WLAN sensing measurement method of an embodiment of the disclosure. Optionally, the method may be performed by an access point (AP), and the method includes the following steps.

[0033]At step 101, a feedback message frame is sent, in which a first operating parameter of the feedback message frame is identical to a second operating parameter of a null data packet announcement (NDPA) frame and/or a third operating parameter of a downlink null data packet (DL NDP) frame.

[0034]As a first example, referring to FIG. 2 to FIG. 4, the WLAN sensing architecture and the WLAN sensing procedure of the WLAN sensing measurement method of embodiments of the disclosure are introduced first.

[0035]FIG. 2 shows a schematic diagram of the architecture involved in the WLAN sensing (procedure). The sensing initiator (or initiator) initiates WLAN sensing (e.g., a WLAN sensing session), and multiple sensing responders (or sensing receivers) or responders may respond to the WLAN sensing, e.g., responder 1, responder 2, and responder 3 in FIG. 2. When the sensing initiator initiates WLAN sensing, multiple associated or unassociated WLAN sensing responders may respond to the WLAN sensing.

[0036]As illustrated in FIG. 3, the sensing initiator communicates with the sensing responder via a communication connection (e.g., as shown by the communication connection S1), and one sensing responder communicates with another sensing responder via a communication connection S2.

[0037]Each sensing initiator may be a client, and each sensing responder (in this example, i.e., responder 1, responder 2, and responder 3) may be a station (STA) or an AP. The STA and the AP may take on more than one role in the WLAN sensing procedure. For example, in the WLAN sensing procedure, the STA may act as a sensing initiator, and the sensing initiator may be a sensing transmitter, a sensing receiver, or both, or neither. In the WLAN sensing procedure, the sensing responder may also be a sensing transmitter, a sensing receiver, or both.

[0038]As another architecture, as shown in FIG. 4, the sensing initiator and the sensing responder may both be clients, and they can communicate with each other by connecting to the same AP. In FIG. 4, Client 1 is a sensing initiator, and Client 2 is a sensing responder.

[0039]Generally, the WLAN sensing procedure includes procedures of WLAN sensing session setup, WLAN sensing measurement setup, WLAN sensing measurement termination, etc. The WLAN sensing procedure mainly includes Triggered Based Sounding (TB) sensing and Non-TB based sensing. In detail, in the TB-based sensing, an AP acts as an initiator or a transmitter. In the Non-TB based sensing, an STA acts as an initiator or a transmitter.

[0040]In the Non-TB based sensing scenario, the AP sends a feedback message frame (i.e., a sensing measurement report) to the STA after completing sensing measurement, and feeds back a measurement result in the feedback message frame. A first operating parameter (or a configuration parameter) of the feedback message frame may be identical to a second operating parameter of an NDPA frame and/or a third operating parameter of a DL NDP frame. Optionally, the first operating parameter, the second operating parameter and/or the third operating parameter include at least one of the following: number of spatial streams (NSS) information, bandwidth (BW) information and TX power information. For example, NSS=1 and BW is 20 MHz bandwidth.

[0041]The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame. In the Non-TB based sensing scenario, the STA sends to the AP the NDPA frame used to indicate sending a null data packet (NDP) frame. The AP receives the NDPA frame, and then sets the operating parameter of the feedback message frame to the second operating parameter of the NDPA frame when sending the feedback message frame subsequently. Optionally, since the first operating parameter is identical to the second operating parameter, there is no need to send indication information for indicating the first operating parameter in the feedback message frame, thereby reducing message overhead.

[0042]The first operating parameter of the feedback message frame may be identical to the third operating parameter of the DL NDP frame sent by the AP to the STA. Similarly, since the first operating parameter is identical to the third operating parameter, there is no need to send indication information for indicating the first operating parameter in the feedback message frame, thereby reducing message overhead.

[0043]As a second example, referring to FIGS. 5 to 7, several Non-TB based sensing scenarios are illustrated, respectively. SIFS stands for Short Inter-frame Space. In detail, referring to FIG. 5, in an initiator to receiver (I2R) sensing sounding (UL sounding) procedure, the sensing initiator (STA) first performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame. The I2R NDP is involved in the sensing measurement. In a receiver to initiator (R2I) sensing sounding (DL sounding) procedure, the sensing responder first performs the third step to send an R2I NDP frame (R2I NDP is not involved in the sensing measurement), and then performs the fourth step to send a feedback message frame to feed back a sounding result. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame.

[0044]As shown in FIG. 6, in an I2R sensing sounding (UL sounding) procedure, the sensing initiator (STA) performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame. The sensing responder (AP) performs the third step to send an R2I NDP frame, and then performs the fourth step to send a feedback message frame. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame and/or the third operating parameter of the I2R NDP frame. In this procedure, both I2R NDP and R2I NDP are involved in the sensing measurement.

[0045]In FIG. 7, in the R2I sensing sounding (DL sounding) procedure, the sensing initiator (STA) first performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame, and I2R NDP is not involved in the sensing measurement. The sensing responder (AP) may perform the third step to execute the DL sounding and send an R2I NDP frame (R2I NDP is involved in the sensing measurement), and then the AP may send a feedback message frame (not shown in FIG. 7). The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame.

[0046]In embodiments of the disclosure, the AP sends the feedback message frame. The first operating parameter of the feedback message frame is identical to the second operating parameter of a NDPA frame and/or the third operating parameter of a DL NDP frame. Embodiments of the disclosure provide a method for feeding back a measurement result in a Non-TB sensing measurement procedure.

[0049]Referring to the first step in FIGS. 5 to 7, the STA sends a sensing NDPA frame to the AP, correspondingly the AP receives the NDPA frame and determines the second operating parameter of the NDPA frame. The NDPA frame is a unicast message frame. The NDPA frame may include an Association ID (AID) of the AP, for example, if the AID is 2043, it indicates that UL sounding is initiated. If the AID is 2047, it indicates that DL sounding is initiated. The NDPA frame may include an optional range of the first operating parameter, such as NSS, BW and other information.

[0053]Referring to the second step in FIGS. 5 to 7, the STA sends an I2R NDP frame (UL NDP frame). Optionally, the operating parameter of the UL NDP frame (e.g., NSS information, BW information, and TX power information) may be the same or different from the operating parameter of the DL NDP frame carried in the NDPA frame. The AP receives the UL NDP frame and performs the third step to send an R2I NDP frame (DL NDP frame) to the STA. Optionally, a number of long training fields (LTFs) in the DL NDP frame is a preset value, for example, 1.

[0054]Optionally, the feedback message frame includes WLAN sensing measurement identification information and/or time information. The sensing measurement identification information may be an instance ID. The time information may be a transmission time of the UL NDP frame, i.e., the time when the STA sends the UL NDP frame. Further, the feedback time of the feedback message frame may be delayed feedback or immediate feedback.

[0055]Optionally, in the embodiments of the disclosure, the first operating parameter, the second operating parameter and/or the third operating parameter are determined during a WLAN sensing session setup procedure or a WLAN sensing measurement setup procedure. For example, in the WLAN sensing measurement setup procedure, the sensing measurement setup ID is determined by the initiator before the sensing measurement. The transmission slot can also be specified in the procedure. For unassociated STAs (i.e., STAs that are not in a communication connection with the AP), a timer synchronization function (TSF) of the AP needs to be obtained in advance.

[0056]In embodiments of the disclosure, the AP sends the feedback message frame. The first operating parameter of the feedback message frame is identical to the second operating parameter of the NDPA frame and/or the third operating parameter of the DL NDP frame. Embodiments of the disclosure provide a method for feeding back a measurement result in a Non-TB sensing measurement procedure.

[0057]FIG. 8 is a flowchart of a WLAN sensing measurement method of an embodiment of the disclosure. Optionally, the method may be performed by a STA, and the method includes the following steps.

[0058]At step 801, a feedback message frame is received, in which a first operating parameter of the feedback message frame is identical to a second operating parameter of an NDPA frame and/or a third operating parameter of a DL NDP frame.

[0059]The adopted WLAN sensing architecture and the WLAN sensing procedure of the WLAN sensing measurement method provided by the embodiment of the disclosure are referred to the description of the preceding first example and will not be repeated herein.

[0060]Generally, the WLAN sensing procedure includes procedures of WLAN sensing session setup, WLAN sensing measurement setup, and WLAN sensing measurement termination, etc. The WLAN sensing procedure mainly includes TB-based sensing and Non-TB based sensing. In detail, in the TB-based sensing, an AP acts as an initiator or a transmitter. In the Non-TB based sensing, an STA acts as an initiator or a transmitter.

[0061]In a Non-TB based sensing scenario, the STA receives a feedback message frame (i.e., a sensing measurement report) sent by the AP after completing sensing measurement, and a measurement result is fed back in the feedback message frame. A first operating parameter (or a configuration parameter) of the feedback message frame may be identical to a second operating parameter of an NDPA frame and/or a third operating parameter of a DL NDP frame. Optionally, the first operating parameter, the second operating parameter and/or the third operating parameter include at least one of the following: NSS information, BW information and TX power information. For example, NSS=1 and BW is 20 MHz bandwidth.

[0062]The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame. In a Non-TB based sensing scenario, the STA sends to the AP an NDPA frame used to indicate sending an NDP frame. The AP receives the NDPA frame, and then sets the operating parameter of the feedback message frame to the second operating parameter of the NDPA frame when sending the feedback message frame subsequently. Optionally, since the first operating parameter is identical to the second operating parameter, there is no need to send indication information for indicating the first operating parameter in the feedback message frame, thereby reducing message overhead.

[0063]The first operating parameter of the feedback message frame may be identical to the third operating parameter of the DL NDP frame sent by the AP to the STA. Similarly, since the first operating parameter is identical to the third operating parameter, there is no need to send indication information for indicating the first operating parameter in the feedback message frame, thereby reducing message overhead.

[0064]As a second example, referring to FIGS. 5 to 7, several Non-TB based sensing scenarios are illustrated, respectively. In detail, referring to FIG. 5, in an I2R sensing sounding (UL sounding) procedure, the sensing initiator (STA) first performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame. The I2R NDP is involved in the sensing measurement. In an R2I sensing sounding (DL sounding) procedure, the sensing responder first performs the third step to send an R2I NDP frame (R2I NDP is not involved in the sensing measurement), and then the AP performs the fourth step to send a feedback message frame to feed back a sounding result. The STA receives the feedback message frame. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame.

[0065]As shown in FIG. 6, in an I2R sensing sounding (UL sounding) procedure, the sensing initiator (STA) performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame. The sensing responder (AP) performs the third step to send an R2I NDP frame, and then the AP performs the fourth step to send a feedback message frame. The STA receives the feedback message frame. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame and/or the third operating parameter of the I2R NDP frame. In this procedure, both I2R NDP and R2I NDP are involved in the sensing measurement.

[0066]In FIG. 7, in the R2I sensing sounding (DL sounding) procedure, the sensing initiator (STA) first performs the first step to send a sensing NDPA frame, and then performs the second step to send an I2R NDP frame, and I2R NDP is not involved in the sensing measurement. The sensing responder (AP) may performs the third step to execute the DL sounding and send an R2I NDP frame (R2I NDP is involved in the sensing measurement), and then the AP may send a feedback message frame (not shown in FIG. 7). The STA receives the feedback message frame. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame.

[0067]In embodiments of the disclosure, the STA receives the feedback message frame. The first operating parameter of the feedback message frame may be identical to the second operating parameter of the NDPA frame and/or the third operating parameter of the DL NDP frame. Embodiments of the disclosure provide a method for feeding back a measurement result in a Non-TB sensing measurement procedure.

[0070]Referring to the first step in FIGS. 5 to 7, the STA sends a sensing NDPA frame to the AP, the AP receives the NDPA frame and determines the second operating parameter of the NDPA frame. The NDPA frame is a unicast message frame. The NDPA frame may include an AID of the AP, for example, if the AID is 2043, it indicates that UL sounding is initiated. If the AID is 2047, it indicates that DL sounding is initiated. The NDPA frame may include an optional range of the first operating parameter, such as NSS, BW and other information.

[0073]Referring to the second step in FIGS. 5 to 7, the STA sends an I2R NDP frame (UL NDP frame). Optionally, the operating parameter of the UL NDP frame (e.g., NSS information, BW information, and TX power information) may be the same or different from the operating parameter of the DL NDP frame carried in the NDPA frame. The AP receives the UL NDP frame and performs the third step to send an R2I NDP frame (DL NDP frame). The STA receives the DL NDP frame. Optionally, a number of LTFs in the DL NDP frame is a preset value, for example, 1.

[0074]Optionally, the feedback message frame includes WLAN sensing measurement identification information and/or time information. The sensing measurement identification information may be an instance ID.

[0075]The time information may be a transmission time of the UL NDP frame, i.e., the time when the STA sends the UL NDP frame. The feedback time of the feedback message frame may be delayed feedback or immediate feedback.

[0076]Optionally, in the embodiments of the disclosure, the first operating parameter, the second operating parameter and/or the third operating parameter are determined during a WLAN sensing session setup procedure or a WLAN sensing measurement setup procedure.

[0077]For example, in the WLAN sensing measurement setup procedure, the sensing measurement setup ID is determined by the initiator before the sensing measurement. The transmission slot can also be specified in the procedure. For unassociated STAs (i.e., STAs that are not in a communication connection with the AP), a TSF of the AP needs to be obtained in advance.

[0078]In embodiments of the disclosure, the STA receives the feedback message frame. The first operating parameter of the feedback message frame is identical to the second operating parameter of the NDPA frame and/or the third operating parameter of the DL NDP frame. Embodiments of the disclosure provide a method for feeding back a measurement result in a Non-TB sensing measurement procedure.

It should also be noted that in some implementations as replacements, the functions labeled in the frames may also be implemented in a different order than those labeled in the accompanying drawings. For example, two consecutively represented boxes may actually be executed substantially in parallel, or they may sometimes be executed in reverse order, depending on the function involved. It should also be noted that each of the frames in the block diagrams and/or flowcharts, and any combination of frames in the block diagrams and/or flowcharts, may be implemented with a specialized hardware-based system that performs the specified function or operation, or may be implemented with a combination of specialized hardware and computer instructions.

[0127]The modules described in the embodiments of the disclosure may be realized through software or hardware. The name of a module does not constitute a limitation of the module itself in a certain case. For example, module A may also be described as “module A for performing an operation B”.

[0128]The above description is only preferred embodiments of the disclosure and an explanation of the technical principles utilized. It should be understood by those skilled in the art that the scope of disclosure involved in the disclosure is not limited to the technical solutions formed by a particular combination of the above technical features, but also covers other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above disclosed concept, for example, the technical solution formed by interchanging the above features with technical features with similar functions disclosed (but not limited to) in the disclosure.
